When thunderclouds begin to gather over Botswana’s Kalahari each year, 20,000 zebras get itchy feet. As the first fat raindrops hit the dust, southern Africa’s biggest animal migration gets underway. In a never-ending quest for grass and water, the striped herds undertake an annual epic trek across the vast lunar landscape of the Kalahari’s Makgadikgadi Pans. See the story of this spectacular annual migration through the eyes of a single zebra family: a stallion, his three mares and their offspring. Documenting their journey across this otherworldly landscape, the film reveals their trials and triumphs as well as the fascinating social bonds that hold zebra families together.
